Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensing probes, in particular to a temperature sensing probe fixing device. Background Art

[0002] A temperature probe is a device used to measure temperature, usually consisting of a sensitive element and a measuring circuit. The sensitive element can be a thermocouple, thermal resistor or semiconductor, etc. They can convert temperature changes into electrical signals, which are then amplified, filtered, converted and processed by the measuring circuit to finally output an electrical signal proportional to the temperature. Temperature probes are widely used in many fields, such as industry, scientific research, medical treatment and environmental protection.

[0003] The existing Chinese patent (CN211717648U) discloses a fixing device for an oven temperature sensing probe, comprising an oven, a card cover fixedly installed on the top inner part of the oven, and a fixing rod is provided in the card cover, the bottom end of the fixing rod extends into the oven and is fixedly installed with a sensing probe, a movable plate is slidably connected to the inner wall of the card cover, and a plug hole is provided on the movable plate, a card column is fixedly installed on the top of the fixing rod, and the top of the card column passes through the plug hole and extends to the top of the movable plate, and wedge blocks are slidably connected to the top of both sides of the card column. The utility model can achieve the effect of braking the fixing rod by inserting the fixing rod into the card cover and pushing the fixing rod upward. The technical solution is convenient in operation and therefore has good practical effects.

[0004] The temperature sensing probe in the above technical solution is often fixed at a certain height in the container after installation and cannot be adjusted. Since the temperatures at different heights in the container are different, when it is necessary to detect the temperatures at different heights in the container, a temperature sensing probe has a small temperature measurement range and it is difficult to ensure accurate temperature measurement at different heights. Utility Model Content

[0005] The purpose of the utility model is to provide a temperature sensing probe fixing device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temperature sensing probe fixing device, comprising: a mounting plate, a long screw and a temperature sensing probe, a threaded sleeve is provided on the middle outer wall of the temperature sensing probe, an inner sleeve is fixed on the outer wall of the threaded sleeve, a bottom lifting ring is fixed on the outer wall of the bottom of the inner sleeve, long screws are provided on both sides of the mounting plate, an outer sleeve is fixed on the bottom end of the long screw, servo motors are provided on both sides of the top of the outer sleeve, a large gear is provided on the top of the servo motor, an outer sleeve limiting plate is provided on the inner wall of the bottom end of the outer sleeve, screws are provided on both sides of the top of the outer sleeve limiting plate, a small gear is provided on the top of the screw, the small gear is meshed with the large gear, and the screw and the bottom lifting ring are connected by a screw nut.

[0007] Furthermore, a locking nut is provided on the outside of the long screw, and the locking nut is located on the upper and lower sides of the mounting plate. A through hole is opened inside the mounting plate on the outside of the long screw, and a screw limiting plate is fixed to the outer wall of the lower half of the long screw.

[0008] Furthermore, a motor mounting frame is provided on the top outer wall of the outer sheath, the servo motor is fixed on the motor mounting frame, a flange is provided on the upper outer wall of the outer sheath, and the bottom end of the long screw is fixedly connected to the top of the flange.

[0010] Furthermore, a bearing seat is provided at the top end of the outer sleeve located in the upper half of the screw rod, and the pinion gear is located above the bearing seat.

[0011] Furthermore, a through hole is provided inside the mounting plate and outside the temperature sensing probe, and an outer wall in the middle of the temperature sensing probe is provided with an external thread, which matches with the internal thread of the threaded sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model realizes that when the temperature sensing probe fixing device is used, the temperature sensing probe and the threaded sleeve are fixed together through the threaded connection by the provided mounting plate, locking nut and temperature sensing probe, so that the temperature sensing probe is fixed. When the height of the temperature sensing probe needs to be adjusted, the locking nut can be loosened so that the long screw can be lifted and lowered relative to the mounting plate, so that the outer sheath fixedly connected to the long screw can be lifted and lowered, thereby driving the temperature sensing probe to be adjusted in height.

Under the action of the lead screw nut, the rotational motion of the lead screw is converted into linear motion with the guidance of the guide rod, thereby driving the bottom lifting ring to rise and fall, and the bottom lifting ring is lifted and lowered to drive the inner sheath fixed thereto to rise and fall, thereby driving the threaded sleeve and the temperature probe to rise and fall, thereby increasing the temperature monitoring range of the temperature probe and improving the accuracy of temperature monitoring at different heights.
